I really like elegant single word titles that have a lot of meanings you can read into them because they feel very modern and clean, so I named my comic "Errant".
It evokes the idea that it's a comic about knights (a knight errant is a wandering knight out doing quests in the world), and when something or someone is "errant" it means they're out of bounds or wandering somewhere, perhaps somewhere unexpected or where they shouldn't be, or even that the person or object is lost.
I also really liked the idea that when attached to things in a wider meta-textual context, it becomes kind of funny. "Errant fans", "Errant merchandise" etc.
